Abstract (en)

Provided herein is a display device and a method of fabricating the same. The display device includes a substrate (BSL) including a display area (DA) and a non-display area (NDA), a via layer (VIA) disposed in the display area, electrodes (ALE1, ALE2, ...) disposed on the via layer and spaced apart from each other, light emitting elements (LD) disposed between the electrodes, dummy pattern layers (DP) disposed in the non-display area, and dummy electrodes (DET) disposed on the dummy pattern layers. The via layer (VIA) and the dummy pattern layers (DP) are disposed on a same layer (PSV) and formed of a same electrically-insulating first material. The electrodes (ALE1, ALE2, ...) and the dummy electrodes (DET) are disposed on a same layer (VIA, resp. DP) and formed of a same electrically-conductive second material.
